Under the Libraries tab on the Right side, I am unable to see the preview of the models or the preview of the Rhino material. I can see the file and I can drag and drop it in, however I can not get a preview of the material or model. I tried viewing them by extra large icons and that did not get it to work. 
Hello - can you see previews in Windows Explorer?
@intuitionusa - see if this helps:

Ok I went into control panel and repaired Rhino… and it works! Thanks. That tutorial is a little out of date but works.
